Just attempted it again with the
14.0-CURRENT-amd64-20220930-42dc8696df5-258315 image, with the
same results. Yet Linux && Windows work as intended. Any thoughts
on how I might track the problem down in FreeBSD?
Thanks.

And in Slackware did it show up as a psm device,
and if it did what IRQ is it using.

Or what I suspect, is it shows up as a USB device.

Mr. Grimes, you're wise well beyond your years.
IOW Thanks! You nailed it.

Now. If I can only figure out why FreeBSD's Synaptics module
only polls psm(4).

Thanks, Rodney!
